I m 14 and I m sexually active, but I went 7 months without sex, and I received a hand job, then the shaft of my penis starting getting a rash and got a cut on it, it s red and spread to my balls, it has bumps and it hurts.. I don t think it s an std but you never know, it s been two months now and it s only gotten worse. My balls are red and have bumbs and do does my shaft, and my penis did but they disappeared, I m uncircumcised if that helps. It s only on the skin, nothing is on the head of my penis, I m scared to go to the doctor. And puss come out of my balls and shaft and it s yellow, please help me. Thank you.
